One of providee device which, is applicable to any automobile having aner zle oi Well fleeting type. object is to provide it device he quicklyand easily attached est to provide 2 device in nee, will permit the reelt remain on the ground thereby the e jack injects are to provide devieeend epewticeig which i not be liable get out 0% erdet, which will becheep to manufacture" Other objects will be in. pert obvious and in partpointed ent hereinafter.

[is shown, this gear is of the usual type andCOIHPIYISGS a main gear 18 which is driven by the main driving shaft andwhich is connected to idlers 14;, it, meshing}: witlilthe beveled gears15, 15,

each ef which is itiormelly' operetively con-- to the inner end of oneof the rem: sezmiexlee. The axles ere operetively connected to thewheels in the usual manner by toothed n'ieinlvers keyed to the axlesheld in. position by nute 15*, and engaging other toothed membersllti'rigidly secured to the Wheels.

From the construction thus far described, which is 01d and Well known,it Wiii be understeod that either of the semiexles may be P moved fromthe axle seeing by merely, nnsciwving the n'zjlts 15* and removing thetootl d member which is geared to the semi-axles, after which the lattermay be dinwn out oi? the casing.

The power ti'ei'isinission device which is adapted to be driven by theengine of the iLlliJOlUOl'L Q, comprises a shaft 17, the inner end ofwhich is adapted to be connected with both of the bevel. gears 15, 15 ofthe 1. The outer end of the shaft 1?, Which pulley or other suitabletrensmisien'lbeir is journaled in? bearing;- 4 iilocit such that whenthe shaft 17 is in position the reel o vzeels 11 may remain on the Queenin order to center the shaft 17 izl 7 a s eve 20 is employed which isslipped ever slmft end which is provided with teeth l on its inner endadapted to engage will the teeth on the member 16. The sleeve 52% isheld 21 iinst longitudinal movee centrally peeforated nut which 1- thesleeve ind is; attached to the 1.6 in manner similar te that by 'wliieiithe nut 15" is The sleeve 20 is preferably provided an eil eup "fer:.lnnwieeting the shaft li'. ntt mixing of the tmnsnlissioi'i device inefor ustb 't'illlfill should be largely obvious from the descriptionflfeliowez-l l hen it c zeiced to operate we drum, which, or otiiemtchinery, enc of semi-axles, for ez-zeniggie the right hand one asshown in 19, the height of which is Fig. 1, is removed as abovedescribed, and the other semi-axle is also removed, or as shown in thefigure, simply withdrawn sufficiently to cause its inner end to move outof engagement with its co-acting bevel gear 15. The centering sleeve 20and nut 22am then placed in position as described and as clearly shownin Fig; 2, after which the shaft 17 is inserted through the sleeve 20and axle casing with its inner end engaging both of the bevel gears 15,15, and its outer end journaled in the bearing 19. The pulley or othertransmission member 18 is then belted or otherwise connected with thedesired machinery, which will be driven when the engine of theautomobile is op erated: When it is again desired to use the automobileas a vehicle, it is merel necessary to remove the shaft 17 and itscentering means 20, and 22, and replace the semiaxles which have beenentirely or partially removed, after which the toothed members which arekeyedto the axles and the nuts are placed in position.

It will be understood from the above description that the powertransmission device is driven through the usual transmission 1 gearing,which is positioned between the engine and the differential gears andthat, therefore, the shaft 17 may be run at different speeds. By soconstructing the device that thewvheels may remain on the ground, it ismerely necessary to block the same to prevent any accidental movement ofthe automobile, and the use of a jack with the con sequent danger of thevehicle slipping there from during the operation of the device isobviated.

Having described this invention in connection with the illustrativeembodiment thereof, to the details of which disclosure the invention isnot of course to be limited, what is claimed as new and what is desiredto be secured by Letters Patent is set forth in the appended claims.

I claim-- 1. In. combination with the difierential gear, a pair ofremovable semi-axles and driving wheels of an automobile, a shaft of'greater length than either of said semiaxles and adapted to have itsinner end operatively connected with said gear, and a transmissionmember carried by said shaft outside of said wheels and adapted torotateindependently of said driving wheels, one of said driving wheels servingas a support 'for said-shaft.

2. In combination with the differential gear, a pair of removablesemi-axles and driving wheels of an automobile, a shaft of greaterlength than either of said semiaxles and adapted to have its inner endoperatively connected with said gear, a .bearing for the outer end ofsaid shaft, and a transmission member carried by said shaft outside ofsaid wheels and adapted to r0- tate independently of said drivingwheels, one of said driving wheels serving as a support for said shaft.

3. In combination with the differential gear and driving wheels of anautomobile, said differential gear comprising a driven gear and a pairof beveled gears engaging therewith, a shaft adapted to have its innerend operatively connected with both of said beveled gears, and atransmission member carried by said shaft outside of said wheels andadapted to rotate inde )cndently of said driving wheels, one of saidriving wheels serving as a support for said shaft.

In combination'witlr the rear axle casing of an automobile, adiffereptial gear, a shaft adapted to be positioned within said casingand having its inner end operatively connected with said differentialgear, the outer end of said shaft extending beyond the outer end of saidcasing, a bearing for the outer end of said shaft, and a transmis sionmember carried by said shaft between said bearing and the outer end ofsaid casing.

7. In combination with the rear axle casing of an automobile, adifferential gear, a pair of removable semi-axles a wheel rotatablysupported by said casing adjacent its outer end, a shaft of greaterlength than either of said semi-axles and extending through said wheeland within said casingand having its inner end operatively connectedwith said differential gear, the outer end of said shaft extendingbeyond said wheel, and a transmission member carried .wheel rotatablysupported by said casing adjacent its outer end, a shaft extendingthrough said Wheel and withln' said casing and having its inner endoperatively connected with said differential gear, the outer end of saidshaft extending beyond said wheel, a bearing for the outer end of saidshaft, and a transmission member car: ried by said shaft and positionedbetween said wheel and said bearing.

9. In combination with the rear axle casing of an automobile, adifferential gear, a pair of'removable semi-axles a wheel rotatablysupported by said casing adjacent its outer end, a shaft of greaterlength than either of said semi-axles and extending through said wheeland Within said casing and having its inner end operatively connectedwith said differential gear, the outer end of said shaft extendingbeyond said wheel, a transmission member carried by said shaft upon theportion extending beyond said wheel and means for centering said shaftrelatively to said wheel,

10. In combination with the rear axle casing of an automobile, adifferential gear, a wheel rotatably supported by said casing adjacentits outer end, said wheel being provided with a toothed member, a shaftextending through said wheel and within. said casing and having itsinner end operatively connected with said differential gear,
